SPDB,
When you consider that GCGC sits on rather gentle terrain, the enormous bunker variety at GCGC is rather unique.
Joel Stewart,
Review of the 1936 aerial reveals that little has changed over those years.
Obviously, the 12th hole was altered and magnificent, deep, fronting and backing horse shoe bunkers were destroyed.
On # 7 a magnificent trench bunker has been allowed to disappear. It's a bunker similar to the trench bunker that borders the right side of # 3 fairway. The trench remains,
but with the shifting of the fairway, maintainance practices and the absence of sand, most golfers never see it.
The 16th hole, left greenside bunker has been lost to a pond, which was the topic of another thread.
The 5th hole and the 14th hole have undergone some changes at the green end, including bunkers.
A bunker was recently reclaimed while being relocated on the right side of # 9 green.
And, unfortunately a bunker/s was/were disfigured recently on the right side of # 17 green.
